Filed: 1988-01-20
Abstract: PURPOSE:To attain correction with simple constitution and high accuracy by correcting the deterioration in the peripheral luminous quantity based on a shading correction signal varied continuously in response to the aperture of an image pickup lens system. CONSTITUTION:The 1st and 2nd parabolic signal generating circuits 4, 5 generate the 1st and 2nd parabolic signals P1, P2 synchronously with horizontal and vertical drive signals HD, VD respectively based on them. An aperture control signal C1 generated by an aperture control circuit 3 increases its level as the aperture of the pickup lens system 1 is being opened to adjust the gain of a 2nd gain control circuit 7 proportional to the level of the signal C1. The sum 9 of the signals P1, P2 is given to the circuit 7 to output a shading correction signal C2 with an, amplitude in response to the aperture. A 1st gain control circuit 6 represents the gain characteristic in response to the aperture under the control of the signal C2 to correct the deterioration in the peripheral luminous quantity in response to the aperture.
